Answer:
The total number of unbroken / working slots
Step-by-step explanation:
Given that Devin's DVD case has 3 rows of slots, but 5 slots are broken
Also given that the number of slots in a row is x
1 row has x slots
3 rows has y slots
on cross multiplication we get y = 3x
ie there are a total of 3x slots in the 3 rows
Given that out of these 3x slots 5 . of the slots are broken
Therefore the total number of working slots = total number of slots - number of slots which are broken
total number of working slots are = 3x - 5
Therefore the given expression is the number of working / good slots
Answer:
an acute triangle
Step-by-step explanation:
an acute triangle has angles that are less than 90 degrees
right triangles have a right angle
obtuse triangles have angles greater than 90 degrees
Answer:
Because they are equal
Step-by-step explanation:
Combine like terms (x's go with x's and y's go with y's) take the sign in from of the value and combine 8x+16x =24x and -9y+12y=3y (combine only works if the variables have the same exponent ( u can combine x and x(because they have an understood exponent of 1) but not x and x^3)
